UPPER MARLBORO, Md. (WUSA) -- Prince George's County Police Arrest Two Teens For Weekend Murder, But Are Looking For One More

In the last 24 hours, police arrested two teens in the weekend murder of a Prince George's County teen, but they are still on the hunt for a third suspect. We've long reported about the no-snitch rule, police's biggest roadblock to solving cases and catching murderers, But days after this senseless shooting between teens in rival gangs, people spoke up, and now two teens are behind bars for the murder of 16-year-old Marcus Jones. Police are hoping your calls and anonymous tips will help them find the last piece of the puzzle.

Prince George's County Police Chief Mark Magaw explains what happened on the night of January 20th, after Marcus Jones left a party, "Akil Darnell Ings, Kquantae Markies Fisher and a yet to be identified 3rd suspect arrived at this party and approached a group outside. Our victim Marcus Jones was standing with this group. Akil Ings produced a firearm and shot Marcus Jones."

Police say Ings is 17, and Fisher is 19. And all are involved in gangs. Magaw says this is the problem, "We believed that these gang associations played a part in this tragic murder."

Which begs the question, what are schools doing about this? Jones is the 4th teen killed in the county this year. Police say the gangs involved in this latest tragedy are called "Baby Haiti," and the "Danger Boys." We talked to Michael Blow, who is in charge of security in all Prince George's County public schools. Blow explained, "We're not besieged with gang activity in these schools, our schools are safe, we're always looking to enhance our safety. Enough of this foolishness were bringing this information forward and hopefully we'll get the result that we saw today."

Police say that third suspect is a black male, in his teens, with a medium build. Not a lot to go on, but they're hoping someone will speak up and say something.
